EINSTEIN AND BESSO MANUSCRIPT

361

ADX.

[79 896].

The document consists of

a 51-page manuscript,

and

additional

text

and calcu-

lations that

were

noted

on a

letter that Einstein had received. Both items

were

found

in

SzGB

after Besso's death. The

manuscript

consists of loose

sheets,

most

of them

single-sided, some

double-sided,

with

no

continuous

numbering.

Roughly

half

the

pages are

in

Einstein's

hand,

the

other half

in

Besso's. The

typed

letter

is

from C.-E.

Guye to Einstein,

31

May 1913

(Vol. 5,

Doc.

443).

Besso added

text

and calculations

to

the

recto

and

verso

of the sheet

on

which this letter

is written,

while Einstein

supplied

two equations.

The

manuscript

and the

handwritten

portions

added

to

the letter

are

reproduced

here in transcribed form.

A

facsimile

reproduction is presented

in

Appendix

B.

The

pages are

numbered

1

through

53

for

this

edition

(recto

and

verso

of

the letter

from

Guye to

Einstein

appear as

[pp.

16-17]).

These

page

numbers

can

be found

in

square

brackets

in

the

upper-left

corner

of the

transcription pages.

The footnotes

are

placed

on

the

page facing

the

transcription

of

the

page

to

which

they

refer

and

are preceded by

the

name(s)

of the main

author(s)

of

that

particular

page.

In

those instances where Besso made

a

small contribution

to

a

page

in

Einstein's

hand,

or

vice

versa,

the reader

is

alerted

to this in

a

footnote.

Two separate sets

of numbers

in

square

brackets

are

added

to the

transcription, one numbering

footnotes

("[1],"

etc.),

the other

one numbering equations ("[eq. 1],"

etc.).

correspond

to

the three

terms
